When building a PR, TRAVIS_BRANCH refers to the *target branch*.
Therefore, if a PR targets `master`, and `master` happened to be tagged,
we skipped the build by mistake.
Fix this by using TRAVIS_PULL_REQUEST_BRANCH (i.e. the *source branch*)
when available, falling back to TRAVIS_BRANCH (i.e. for CI builds, also
known as "push builds").

Sometimes, failures in a test case are actually caused by issues in
earlier test cases.
To make it easier to see those issues, let's attach the output from
before the failing test case (i.e. stdout/stderr since the previous
failing test case, or the start of the test script). This will be
visible in the "Attachments" of the details of the failed test.

The JUnit XML format lends itself to be presented in a powerful UI,
where you can drill down to the information you are interested in very
quickly.
For test failures, this usually means that you want to see the detailed
trace of the failing tests.
With Travis CI, we passed the `--verbose-log` option to get those
traces. However, that seems excessive, as we do not need/use the logs in
almost all of those cases: only when a test fails do we have a way to
include the trace.
So let's do something different when using Azure DevOps: let's run all
the tests with `--quiet` first, and only if a failure is encountered,
try to trace the commands as they are executed.
Of course, we cannot turn on `--verbose-log` after the fact. So let's
just re-run the test with all the same options, adding `--verbose-log`.
And then munging the output file into the JUnit XML on the fly.
Note: there is an off chance that re-running the test in verbose mode
"fixes" the failures (and this does happen from time to time!). That is
a possibility we should be able to live with. Ideally, we would label
this as "Passed upon rerun", and Azure Pipelines even know about that
outcome, but it is not available when using the JUnit XML format for
now:

When running the p4 daemon or `git daemon`, we want to kill it at the
end of the test script.
So far, we do this "manually".
However, in the next few commits we want to teach the test suite to
optionally re-run scripts with different options, therefore we will have
to have a consistent way to stop daemons.
Let's introduce `test_atexit`, which is loosely modeled after
`test_when_finished` (but has a broader scope: rather than running the
commands after the current test case, run them when the test script
finishes, and also run them when the `--immediate` option is in effect).

This commit adds an azure-pipelines.yml file which is Azure DevOps'
equivalent to Travis CI's .travis.yml.
To make things a bit easier to understand, we refrain from using the
`matrix` feature here because (while it is powerful) it can be a bit
confusing to users who are not familiar with CI setups. Therefore, we
use a separate phase even for similar configurations (such as GCC vs
Clang on Linux, GCC vs Clang on macOS).
Also, we make use of the shiny new feature we just introduced where the
test suite can output JUnit-style .xml files. This information is made
available in a nice UI that allows the viewer to filter by phase and/or
test number, and to see trends such as: number of (failing) tests, time
spent running the test suite, etc.

This will come in handy when publishing the results of Git's test suite
during an automated Azure DevOps run.
Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
In the next commit, we want to teach Git's test suite to optionally
output test results in JUnit-style .xml files. These files contain
information about the time spent. So we need a way to measure time.
While we could use `date +%s` for that, this will give us only seconds,
i.e. very coarse-grained timings.
GNU `date` supports `date +%s.%N` (i.e. nanosecond-precision output),
but there is no equivalent in BSD `date` (read: on macOS, we would not
be able to obtain precise timings).
So let's introduce `test-tool date getnanos`, with an optional start
time, that outputs preciser values.
Granted, it is a bit pointless to try measuring times accurately in
shell scripts, certainly to nanosecond precision. But it is better than
second-granularity.

This merging-rebase does not change anything in the code, just in the
commit structure of Git for Windows' branch thicket.
The motivation for this is that we have accumulated tons and tons of
patches in various stages of readiness to be contributed to core Git,
but there is no clear picture which patches are the most ready.
So here we use the calmer post-release days to organize our existing
branches into a more coherent structure, reordering them in order of
priority, and we also take the opportunity to merge branches (e.g.
misc-vs-fixes-extra into misc-vs-fixes) as well as patches (e.g. "The
stat() function should be independent of core.symlinks" really wanted to
be a fixup! commit for "Win32: implement stat() with symlink support").

In 9ac3f0e5b3 (pack-objects: fix performance issues on packing large
deltas, 2018-07-22), a mutex was introduced that is used to guard the
call to set the delta size. This commit even added code to initialize
it, but at an incorrect spot: in `init_threaded_search()`, while the
call to `oe_set_delta_size()` (and hence to `packing_data_lock()`) can
happen in the call chain `check_object()` <- `get_object_details()` <-
`prepare_pack()` <- `cmd_pack_objects()`, which is long before the
`prepare_pack()` function calls `ll_find_deltas()` (which initializes
the threaded search).
Another tell-tale that the mutex was initialized in an incorrect spot is
that the function to initialize it lives in builtin/, while the code
that uses the mutex is defined in a libgit.a header file.
Let's use a more appropriate function: `prepare_packing_data()`, which
not only lives in libgit.a, but *has* to be called before the
`packing_data` struct is used that contains that mutex.
This fixes https://github.com/git-for-windows/git/issues/1839.

There is a problem in the way 9ac3f0e5b3 (pack-objects: fix
performance issues on packing large deltas, 2018-07-22) initializes that
mutex in the `packing_data` struct. The problem manifests in a
segmentation fault on Windows, when a mutex (AKA critical section) is
accessed without being initialized. (With pthreads, you apparently do
not really have to initialize them?)
This was reported in https://github.com/git-for-windows/git/issues/1839.

This trick was performed by rebasing the builtin-stash-rebase-v2 branch
thicket via `git rebase -ki --rebase-merges=rebase-cousins v2.19.1`,
replacing all branches that made it into `pu` by their current versions
(and also the builtin-stash by the newest iteration as of ungps/git),
labeling the branch as `builtin-stash-rebase-v3` and then replacing it
in the `merge` command in the todo list.
We did have to rebase the "cousins" because the initial merge of a
merging-rebase will confuse the merge-base logic (and hence the changes
would be dropped when we try to merge them "again").

This is part two of the Ctrl+C story, where part one is
https://github.com/git-for-windows/MSYS2-packages/commit/f4fda0f30aa.
Part one took care of extending the signal handling in the MSYS2 runtime
such that non-MSYS2 processes "receive" a SIGINT by injecting a remote
thread that runs kernel32!CtrlRoutine as if GenerateConsoleCtrlHandler()
had been called (but in contrast to the latter, only one process is
targeted at a time, not every process attached to the same Console) into
the process that needs to be interrupted as well as into all of the
spawned child processes.
Part two now takes care of removing the misguided "kill all spawned
children" atexit() handler, and it also installs a ConsoleCtrl handler
to run Git's SIGINT handlers, such as the one waiting for the pager to
exit.

Previously, we did not install any handler for Ctrl+C, but now we really
want to because the MSYS2 runtime learned the trick to call the
ConsoleCtrlHandler when Ctrl+C was pressed.
With this, hitting Ctrl+C while `git log` is running will only terminate
the Git process, but not the pager. This finally matches the behavior on
Linux and on macOS.
